CC -!- FUNCTION: Transcription factor that can activate or repress
CC transcription in response to physiological and pathological stimuli.
CC Binds with high affinity to GC-rich motifs and regulates the expression
CC of a large number of genes involved in a variety of processes such as
CC cell growth, apoptosis, differentiation and immune responses. Highly
CC regulated by post-translational modifications (phosphorylations,
CC sumoylation, proteolytic cleavage, glycosylation and acetylation).
CC Binds also the PDGFR-alpha G-box promoter. May have a role in
CC modulating the cellular response to DNA damage. Implicated in chromatin
CC remodeling. Plays an essential role in the regulation of FE65 gene
CC expression. In complex with ATF7IP, maintains telomerase activity in
CC cancer cells by inducing TERT and TERC gene expression. Isoform 3 is a
CC stronger activator of transcription than isoform 1. Positively
CC regulates the transcription of the core clock component ARNTL/BMAL1

CC -!- TISSUE SPECIFICITY: Up-regulated in adenocarcinomas of the stomach (at
CC protein level). Isoform 3 is ubiquitously expressed at low levels.
CC {ECO:0000269|PubMed:21798247}.
CC -!- INDUCTION: By insulin. {ECO:0000269|PubMed:16332679}.
CC -!- DOMAIN: The 9aaTAD motif is a transactivation domain present in a large
CC number of yeast and animal transcription factors.
CC {ECO:0000269|PubMed:31375868}.
CC -!- PTM: Phosphorylated on multiple serine and threonine residues.
CC Phosphorylation is coupled to ubiquitination, sumoylation and
CC proteolytic processing. Phosphorylation on Ser-59 enhances proteolytic
CC cleavage. Phosphorylation on Ser-7 enhances ubiquitination and protein
CC degradation. Hyperphosphorylation on Ser-101 in response to DNA damage
CC has no effect on transcriptional activity. MAPK1/MAPK3-mediated
CC phosphorylation on Thr-453 and Thr-739 enhances VEGF transcription but,
CC represses FGF2-triggered PDGFR-alpha transcription. Also implicated in
CC the repression of RECK by ERBB2. Hyperphosphorylated on Thr-278 and
CC Thr-739 during mitosis by MAPK8 shielding SP1 from degradation by the
CC ubiquitin-dependent pathway. Phosphorylated in the zinc-finger domain
CC by calmodulin-activated PKCzeta. Phosphorylation on Ser-641 by PKCzeta
CC is critical for TSA-activated LHR gene expression through release of
CC its repressor, p107. Phosphorylation on Thr-668, Ser-670 and Thr-681 is
CC stimulated by angiotensin II via the AT1 receptor inducing increased
CC binding to the PDGF-D promoter. This phosphorylation is increased in
CC injured artey wall. Ser-59 and Thr-681 can both be dephosphorylated by
CC PP2A during cell-cycle interphase. Dephosphorylation on Ser-59 leads to
CC increased chromatin association during interphase and increases the
CC transcriptional activity. On insulin stimulation, sequentially
CC glycosylated and phosphorylated on several C-terminal serine and
CC threonine residues. {ECO:0000269|PubMed:11904305,

CC ECO:0000269|PubMed:18258854, ECO:0000269|PubMed:18619531}.
CC -!- PTM: Acetylated. Acetylation/deacetylation events affect
CC transcriptional activity. Deacetylation leads to an increase in the
CC expression the 12(s)-lipooxygenase gene though recruitment of p300 to
CC the promoter. {ECO:0000269|PubMed:16478997}.
CC -!- PTM: Ubiquitinated. Ubiquitination occurs on the C-terminal
CC proteolytically-cleaved peptide and is triggered by phosphorylation.
CC {ECO:0000269|PubMed:18239466}.
CC -!- PTM: Sumoylated with SUMO1. Sumoylation modulates proteolytic cleavage
CC of the N-terminal repressor domain. Sumoylation levels are attenuated
CC during tumorigenesis. Phosphorylation mediates SP1 desumoylation.
CC -!- PTM: Proteolytic cleavage in the N-terminal repressor domain is
CC prevented by sumoylation. The C-terminal cleaved product is susceptible
CC to degradation.
CC -!- PTM: O-glycosylated; Contains 8 N-acetylglucosamine side chains. Levels
CC are controlled by insulin and the SP1 phosphorylation states. Insulin-
CC mediated O-glycosylation locates SP1 to the nucleus, where it is
CC sequentially deglycosylated and phosphorylated. O-glycosylation affects
CC transcriptional activity through disrupting the interaction with a
CC number of transcription factors including ELF1 and NFYA. Also inhibits
CC interaction with the HIV1 promoter. Inhibited by peroxisomome
CC proliferator receptor gamma (PPARgamma).
CC -!- MISCELLANEOUS: In the hepatoma cell line Hep-G2, SP1 precursor mRNA may
CC undergo homotype trans-splicing leading to the duplication of exons 2
CC and 3.
CC -!- SIMILARITY: Belongs to the Sp1 C2H2-type zinc-finger protein family.
